COMBINATION STENCIL-SHEET.

Specification of Letters Patent. Patented Feb. 22 1921 Application filedMay 26, 1920. Serial No. 384,327.

To all whom it may concern:

Be it known that I, SVERRE RIAN, a citizen of the United States, and aresident of Darlington, in the county of Lafayette and State ofWisconsin, have invented new and useful Improvements in CombinationStenoil-Sheets, of which the following is a specification.

My invention is a stencil sheet and the principal object thereof is toprovide a stencil sheet wherein any combination of outlines of theletters of the alphabet and numerals may be formed.

Further the invention provides a combination stencil sheet wherein asystem of guide lines are so combined on the sheet as to enable one totrace or form the outline of any letter or number.

The invention further provides a stencil sheet wherein guide marks orcharacters are arranged with respect to the various letters or numbersto enable the operator to readily plot the character about to be formed,thus eliminating the possibility of confusion, due to the many linesintersecting each other.

Another object of my invention is to provide a stencil sheet of thischaracter which ma be used by the average person and wlnch is ofcomparatively simple construction.

With the preceding and other objects, as may become apparent from thedisclosure, the invention consists in the sheet together with thecombination of various guide lines or'slots so combined as to form anyletter or number, and which will be hereinafter outlined and claimed.

The invention being illustrated in the accompanying drawing, wherein:

Figure 1 is a plan view of the stencil sheet;

Fig. 2 is a fragmentary sectional view of the same, illustrating amarking element engaged in one of the guide slots.

Referring in detail to the drawing, wherein like characters designatecorresponding parts throughout the several views, the numeral 5designates a rectangular sheet which vmay be celluloid, aluminum orother light sti material.

In carrying out the invention, the sheet 5 is provided with a system ofwhat shall be termed as guide lines, each of which is aninterrupted-line of slots and perforations.

to line 14 and line 29 extends One set of these guide lines extends atspaced intervals in parallel relation across the sheet andare numberedfrom 6 to 10 inelusive.

A set of supplemental lines, indicated at 11, are arranged inparallelrelation to the first mentioned lines and are disposed atpredetermined distances with respect to these lines. Intersecting thelines from 6 to 11 inclusive and disposed at right angles thereto 1s aplurality of lines numbered from 12 to 17 inclusive. I

A plurality of lines numbered from 18 to 22 extend diagonally from leftto right across the sheet, and each of the lines 19 to 22 with one ofthe lines 6 and a line connectlng the same forms a triangle, while theline 18 with the left hand lower marginal edge of the sheet 5 forms atriangle. The l1ne 19 stops at a point at the intersection of lines 8and 16, while line 20 extends to the point of intersection of the lines10 and 17, the remaining lines extend entirely across the sheet.

A plurality of lines numbered from 23 to 32 inclusive extend diagonallyacross the sheet from right to left and with the right marginal edge orthe parallel lines 6 to 10 form a triangle; the lines 23, 25, 26 and 28are parallel, while lines 24, 27, 29, 31 and 32 are at a differentrelative pitch.

Line 24 stops at line14 and line 25 extends from the lower marginal edgeof the sheet to line 15. Line 28 also extends from the lower marginaledge of the sheet from the upper marginal ed e of the sheet at line 9and intersects ines 14 and extends to the lower marginal edge of thesheet. Line 30 extends from line 8 at line 14 to the lower marginal edgeof the sheet and line-31 extends from line 8 at one end and stops atline 15 while line 32 intersects line 7 at line 14 and extends to theleft marginal edge of the sheet.

Pairs of divergent lines 33 extend from points between lines 12 and 13and 15 and 16 at the right marginal edge of the sheet and which touch onthe line 10 at lines 14 and 17 and 16 and 12.

Pairs of divergent lines 34, whose degree of divergence is less than thelines 32, extend from points between lines 12 and 13 and '16 and 17respectively; one line of each of the latter intersects one line of eachpair of divergent lines 32 and stop at line 10, while the other line ofeach "pair touches the opposite mar inal edge ofthe sheet.

At the left of t 1e sheet, there are circular lines 35 Whose radius iswithin each other, and in the center of each of these circles is asmaller circle 36, one of these latter circles touches on lines 12 and14 while the other touches on lines 15 and 17 being of a diameter equalthe distance between each pair of these lines.

In order to indicate the starting point of various letters and numbers,of similar make-up, such as R,'B, P and D, groups of letters areinscribed on the sheet as illustrated in the drawin Another illustrationwould be H, K, E, and M. In making a letter or figure and in order toplot the same quickly, and in order to follow the correct lines,characters surround the outlines of the various letters, such as forexample, the letter U is arranged at opposite sides of each parallelline of the outline of the U on the sheet.

It is to be understood that the form of my invention herein shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape,

and protect by Letters Patent of the United States, 1s:

1. A combination stencil sheet having interrupted guide openingsthereinarranged with respect to each other so that certain combinations ofopenings form certain char-- acters, and also havin groups of charactersof similarity inscribe on the sheet to indicate the starting point ofcertain characters within a certain area of the sheet.

2. A combination stencil sheet having interrupted guide openings thereinarranged with respect to each other so that certain combinations ofopenings form certain characters, and also havin groups of characters ofsimilarity inscribe on the sheet to-indi-- cate the starting point ofcertain characters within a certain area of the sheet, the sheet beingfurther provided with characters at points formin the outline of thevarious characterson t e stencil sheet.

SVERRE RIAN.
